Address Resolution Protocol (ARP) a stateless protocol was designed to map Internet Protocol addresses (IP) to their associated Media Access Control (MAC) addresses.
This being said, by mapping a 32 bit IP address to an associated 48 bit MAC address via attached Ethernet devices, a communication between local nodes can be made.

Definitely B) ARP. It's a common target for hackers.

Agreed! ARP doesn't authenticate requests, making it easy for attacks.

ARP is the one that maps addresses, no doubt!

Wait, are we sure about that? I feel like there’s more to it.

I thought it was RARP? Seems like a tricky question.

I feel like ICMP is more about error messages and not really related to address mapping, so I think it has to be ARP.

I’m a bit confused between ARP and RARP. I know both deal with address mapping, but I can't recall which is more susceptible to MITM.

I remember practicing questions about ARP and its vulnerabilities, so I feel like it’s definitely the right answer here.

I think ARP is the one that maps addresses, but I'm not entirely sure if it's the most vulnerable to MITM attacks.
